It would depend on the material thickness, the size of the welds, positions, whether you can meet prequalification requirements or not.

If by EH36, you are referring to ABS EH36, it is a prequalified base metal. Provided you meet the other conditions of prequalification as delineated by Clause 3 of D1.1, you should be ready to weld once you write a prequalified WPS.
